The technical scheme of the utility model is that: a flow divider for an air conditioning unit comprises a flow dividing head and a main flow pipe, wherein the flow dividing head comprises a flow dividing hole section and a cavity section, the flow dividing hole section is provided with a plurality of flow dividing holes which are uniformly distributed along the circumferential direction, the cavity section is provided with a cavity which is concave and is communicated with the flow dividing holes, the center of the cavity is provided with a flow guiding cone which is convex along the axial direction, and the inner wall of the end part of the cavity section is provided with a chamfer; the main flow pipe is divided into an assembly section, an inclined section and an inlet section which are sequentially connected along the length direction, an annular limiting boss for limiting the end face of the assembly section is arranged in the cavity, the outer side face of the assembly section is matched with the inner side face of the cavity section so as to be assembled with the flow dividing head into a whole, a mixing cavity for fluid to flow is formed between a flow guide cone of the flow dividing head and the main flow pipe, and the main flow pipe is sequentially provided with an expanding cavity and a total liquid inlet cavity below the mixing cavity; the inner ends of a plurality of shunting holes of the shunting head are respectively communicated with the mixing cavity; the inner side of the end face of the assembling section is tangent to the outer side of the shunting hole, the outer side of the end face of the assembling section is in interference fit with the inner wall of the cavity section, and the outer side of the tail end of the assembling section is tangent to the chamfer angle of the inner wall of the end part of the cavity section.

In a further technical scheme, the shunting holes are arranged in a 2 multiplied by 2 mode.

The utility model has the advantages that:

the utility model discloses a cooperation to mainstream pipe assembly section and reposition of redundant personnel first cavity section is improved, and the junction of mainstream pipe assembly section and reposition of redundant personnel first cavity section forms interference fit to when avoiding welded fastening, the molten drop after the heating flows into the hybrid chamber from the space between mainstream pipe and the reposition of redundant personnel, thereby blocks up the hybrid chamber.

FIG. 2 is a schematic view of the flow-splitting head of FIG. 1;

fig. 3 is a schematic view of the main flow tube structure of fig. 1.

The device comprises a flow dividing head 1, a flow dividing head 11, a flow dividing hole section 12, a flow dividing hole 13, a cavity section 14, a cavity 15, a chamfer 16, a flow guiding cone 17, a limiting boss 2, a main flow pipe 21, an assembly section 22, an inclined section 23, an inlet section 3, a mixing chamber 4, an expansion chamber 5 and a total liquid inlet chamber.

Detailed Description

The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.

As shown in fig. 1-3, the utility model relates to a shunt for air conditioning unit, including reposition of redundant personnel head 1 and mainstream pipe 2, reposition of redundant personnel head 1 is including reposition of redundant personnel hole section 11 and cavity section 13, and reposition of redundant personnel hole section 11 is equipped with along a plurality of reposition of redundant personnel holes 12 of circumference evenly distributed, cavity section 13 is equipped with the indent and with the cavity 14 of a plurality of reposition of redundant personnel hole 12 intercommunications, and reposition of redundant personnel hole 12 is 2 x 2 in this embodiment and arranges.

A flow guide cone 16 protruding in the axial direction is arranged in the center of the cavity 14, and a chamfer 15 is arranged on the inner wall of the end part of the cavity section 13; the main flow pipe 2 is divided into an assembly section 21, an inclined section 22 and an inlet section 23 which are sequentially connected along the length direction, an annular limiting boss 17 used for limiting the end face of the assembly section 21 is arranged in the cavity 14, the outer side face of the assembly section 21 is matched with the inner side face of the cavity section 13 so as to be assembled with the flow dividing head 1 into a whole, a mixing cavity 3 for fluid to flow is formed between a flow guide cone 16 of the flow dividing head 1 and the main flow pipe 2, and the main flow pipe 2 is sequentially provided with an expanding cavity 4 and a total liquid inlet cavity 5 below the mixing cavity 3; the inner ends of a plurality of shunting holes 12 of the shunting head 1 are respectively communicated with the mixing cavity 3; the inner side of the end face of the assembling section 21 is tangent to the outer side of the diversion hole 12, the outer side of the end face of the assembling section 21 is in interference fit with the inner wall of the cavity section 13, and the outer side of the tail end of the assembling section 21 is tangent to the chamfer 15 of the inner wall of the end part of the cavity section 13. Therefore, the outer diameter of the end of the fitting section 21 is smaller than that at the upper end face.

During welding, because the outer diameter of the tail end of the assembling section 21 is smaller than the outer diameter of the end face, a gap can be prevented from being generated between the assembling section 21 and the cavity section 13, the phenomenon that molten drops easily permeate into the mixing cavity 3 along the gap is further avoided, and the welding blockage phenomenon of the mixing cavity 3 is avoided.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
